Unoptimized Images

Overview

Optimized images take less time to download, resulting in faster page
loads. Page load time is one of the most important metrics for how users
perceive the performance of your site. See Load: Deliver content under
1000ms to learn more.

Recommendations

For simple geometric shapes like logos, use a vector format like SVG, as it
can significantly reduce file size.

For complex images like photos, use WebP wherever possible. Browser support
is not universal, though, so you'll need to use fallback mechanisms when
WebP is not available. See How can I detect browser support for
WebP? for an overview of techniques.
